遇到電腦音箱發出電流聲，即便靜音也無法消除的困擾嗎？ php小編新一發現，這個問題困擾著不少用戶。造成電腦音箱電流聲的原因可能是多方面的，可能是驅動程式問題、主機板不相容、音效卡問題、甚至電源問題。下面，php小編新一將為大家一一分析這些原因，並提供解決方法。
1、電源變壓器幹擾
由電源漏磁造成，可以透過為變壓器加裝鐵型材料製作的屏蔽罩來阻擋漏磁，也可以使用外置變壓器。最根本的，還是要選擇大品牌、用料紮實的產品。
2、雜散電磁波幹擾
雜散電磁波幹擾是比較常見，電腦主機、音箱導線、分頻器、無線設備都可能成為音箱的干擾源，在條件允許情況下，應將主機箱盡量遠離電腦主機、手機等電子設備。
1、插卡不正，音效卡沒有同主機板擴充槽嚴密分離，經過目視可見音效卡上「金手指」與擴充槽簧片有錯位現象。這種現像在ISA卡或PCI卡上都有，屬於常見毛病，想方法讓音效卡插正就能夠處理問題了。
2、有源音箱輸入端接在了聲卡的Speaker輸出端，有源音箱應接在聲卡的Line-Out端，它輸出的信號沒有經過聲卡上的放大，噪聲要小得多。有的音效卡只要一個輸出端，是Line-Out還是Speaker要靠卡上的跳線決議，默許方式常常是Speaker，所以假如需求的話，還得拔下聲卡調整跳線。
3、裝置的聲卡驅動程序的版本不好，你可能用的是系統自帶的驅動程序，假如是這樣，最好裝置特地的聲卡驅動程序
解決方法如下
檢查音頻線和電源供電是否正確；查看是否有電磁幹擾。操作步驟：
1、檢查介面是否插接正確，透過與電腦綠色音訊介面連接，音效卡 面板中的粉紅色介面通常用來連接麥克風，如果因此接錯音響也會發出微弱的電流聲。
2、查看一下電源供電是否正確，過高的供電電壓將導致音響內部產生電流聲。
3、部分音響出現「電源」等噪音現像是因為軟體設定不當造成。
4、採取以下方法來解決：打開“控制面板”，點擊“聲音和音頻”-“管理音頻設備”進入。
5、電磁幹擾也會導致音響發出電流聲，將手機、微波爐等易產生電磁的設備遠離音響可。
原因和解決辦法：
1、聲卡驅動程序問題
你可能用的是系統自帶的驅動程序，或驅動有問題，如果是這樣，可以換一個聲卡驅動程序。
2、插卡不正
聲卡沒有同主機板擴充槽嚴密分離，經過目視可見聲卡上金手指?;與擴充槽簧片有錯位現象。
這種現像在isA卡或Pci卡上都有，屬於常見毛病，想方法讓聲卡插正就能夠處理問題了。
電腦桌上型電腦插音響沒有聲音，只有電流聲，先要看是音響的問題還是電腦的問題，或是訊號線有沒有問題，要有針對性的找，可以先用耳機聽聽，看電腦輸出是否有，有就是音響問題，無就要找電腦故障，電腦問題只有音效卡，驅動或設置，還有耳機插孔。
電腦音響滋滋聲，原因是音效卡驅動故障，電磁幹擾，音訊介面的故障。具體原因和解決方法如下：
1、電腦音箱有滋滋聲響大多是聲卡驅動造成的問題，需要卸載原聲卡驅動後重新安裝，右鍵單擊“計算機”並且點擊“設備管理器”，在“設備管理員”中，我們點開“聲音、視頻和遊戲控制器”，點開後出現子列表，列如“Realtek High Definition Audio”，在此欄上右鍵單擊後彈出菜單選擇，使用驅動精靈或者驅動人生軟體安裝音效卡驅動即可。
2、由於電磁幹擾出現電腦音響發出滋滋聲音，需要把主機或手機遠離電腦音箱。
3、也可能是音頻接口的故障，主機上前後都有音頻接口，需要前後音頻接口都測試下，可以自行購買一個USB聲卡查到主機上使用。
所以，電腦音響發出滋滋聲音的原因是聲卡驅動故障，電磁幹擾，音頻接口的故障。
請拔掉音箱的音頻輸入線插頭，如果還有電流聲，就是音箱功放問題，如果沒有電流聲了，就是電腦聲卡問題。
If it is determined to be a speaker problem, the current sound can be changed by adjusting the volume potentiometer. It should be a pre-stage problem, not a problem with the power supply. If the filter capacitor in the power supply part fails, the current sound will not change with the volume potentiometer adjustment. Change.
Please check whether the power supply filter capacitor of the pre-op amplifier is open circuited or failed, and whether the op amp integrated block is damaged.
Check whether the audio cable and power supply are correct; check whether there is electromagnetic interference. Operation steps:
1. Check whether the interface is plugged in correctly. Connect it to the green audio interface of the computer. The pink interface in the sound card panel is usually used to connect the microphone. If the wrong speaker is connected, a weak current sound will be emitted.
2. Check whether the power supply is correct. Excessive power supply voltage will cause current sound inside the speaker.
3. "Power supply" and other noise phenomena in some speakers are caused by improper software settings.
4. Take the following methods to solve the problem: Open the "Control Panel", click "Sound and Audio" - "Manage Audio Devices" to enter.
5. Electromagnetic interference will also cause the speaker to emit current sound. Keep mobile phones, microwave ovens and other devices that are prone to electromagnetic generation away from the speaker.
6. Switch to the "Playback" tab, select "Player" and click "Properties" to enter.
7. Switch to "Enhance" in the window that opens, check "Disable all sound effects", and click "OK" to complete the settings.
8. If the above methods cannot solve the problem, it may be that the audio hardware itself is faulty, and you can only send it to a repair center for repair. Welcome to download Tencent Computer Manager to learn more knowledge and experience more functions.
The sound of current coming from the computer host is one of the problems that many users often encounter when using computers. When we turn on the computer, if we hear the sound of electricity coming from the computer host, sometimes it will make people feel troubled and worried. The occurrence of this sound may be caused by different reasons. Today we will discuss the possible causes and solutions of the current sound in the computer host.
The power supply is an essential component for the normal operation of the computer. If there is a problem with the power supply, it may cause the computer host to emit a current sound. One possible reason is that the internal components of the power supply are damaged or aged, resulting in unstable current and thus noise.
The fan in the computer host is responsible for dissipating heat. If the fan fails or accumulates dust, it may make a roar or a current sound. A poorly running fan can cause the computer to overheat, affect computer performance, and even shorten the life of the hardware.
The hard drive in the computer host may also emit current sounds when working. The read-write head of the hard disk will produce a certain sound when reading data. However, if the sound is abnormally loud or harsh, there may be a problem with the hard disk. It is recommended to back up important data and repair or replace it as soon as possible.
For the problem of electric current sound in the computer host, you can first try to clean the internal components. Turn off the computer and disassemble the host. Use professional cleaning tools to clean the internal components and fans to remove dust and debris to ensure smooth air circulation and help reduce noise.
If the computer host continues to make a current sound, it is recommended to check whether the power supply is normal. Professional tools can be used to test whether the power output voltage is stable. If there is any abnormality, the power supply should be replaced in time to avoid affecting hardware operation and data security.
If there is a problem with the hard drive or other hardware after inspection, it is recommended to replace the damaged parts in time. Choose high-quality and reliable hardware components to ensure compatibility and stability, and fundamentally reduce the possibility of the computer host emitting current noise.
The sound of current in the computer host may be caused by power supply problems, fan failure or hard disk problems. For these problems, we can eliminate the current sound and ensure the normal operation of the computer by cleaning internal components, checking the power supply, and replacing hardware. Regular computer maintenance and upkeep is the key to maintaining computer stability and performance. I hope the above content can help users who encounter similar problems.
It’s because your power connection is unstable, which causes the sound of current
